China diesel generator prices and factor analysis

The so-called “gas” refers to the ice maker engine intake and exhaust system. Turbocharged diesel engine exhaust pressure by blowing the turbine wheel to drive high-speed rotary pump, compressed air to the intake pipeline. Ensure the engine’s power. Therefore, the turbocharged diesel engine intake and exhaust system must be completely sealed. If the exhaust pipe or fittings leak, the exhaust pressure drop, drop turbocharger speed, engine inlet pressure decreases, the engine power falls. Intake system includes intake, intercooler and all connectors if you leak, then although the intake turbocharger pressure to provide standard, but the real amount of air entering the engine will be significantly less, so that the engine power down. This failure often occurs after the repair and maintenance, re-assembled into, drainage systems caused by leaking.
Worth noting that the governor in the fuel diesel generator on (FM pump), or on the fuel pump (Bosch pump) to install a set of smoke limiter, which is connected with the intake pipe of a gas pipeline smoke limiter to detect the engine oil supply inlet pressure to control the amount of gear lever to adjust the fuel injection quantity and fuel supply air to maintain a reasonable match at any time, so when the engine suddenly accelerated to eliminate turbocharger lag caused by smoke. If the gas pipeline connection fittings leak, can also cause lack of engine power. The failure often occurs after the repair and maintenance disassembly line.
Engine maintenance to ensure grupos geradores condition of the vehicle recovery, the correct match is very important to the piston assembly. As the cylinder, piston, piston pin and piston rings in the engine working conditions, state of motion, so is not the same material is not the same as the relationship between the various components and requirements, but also more complex. In the engine assembly plant in order to obtain high-precision, engine piston group of the “four elements”? Font cylinders, pistons, piston pins and piston rings are usually grouped according to the actual size, the size of the same group of assembled parts, such as miniature cars 462Q engine assembly to ensure that the engine cylinder and piston skirt has a good choice in front of the piston and cylinder group assembled to ensure proper distribution of the gap between piston and cylinder-cylinder.
Engine cylinder piston and piston rings in pad printer, is a typical sliding friction, and because of the cylinder and piston friction coefficient of expansion vary widely, so a campaign to ensure its normal state, to pay attention to the Pistons’ four components, ” assembly related and interdependent, may also affect the relationship between the size. Assembly relationship, although the surface is independent, but in the overall design, all components must be taken into account to determine the relationship between the General Assembly meeting a reasonable size, constitute a single dimension chain. If a part size changes or exceed its tolerance range, the destruction of its assembly dimension chain, thus affecting the machine assembly, maintenance, quality quality, mechanical skills. Cylinder should be clean and equipped with the right choice and the cylinder gap is too large will cause knock, power down; and the cylinder gap is not too small, too small will result in a “cylinder.” Gap will choose the wrong distribution in the cylinder-cylinder Piston take in the open space, extension, the degree of change in technical parameters of the impact of leaking the results of the normal operation of the piston rings.
Turn off after the diesel generator cooling silent diesel generator, heat capacity sharply reduced, heat loss of cooling parts, could easily lead to the cylinder head, cylinder liner, cylinder block and other parts overheating, cracks, or excessive expansion of the piston stuck in the cylinder in. On the other hand, diesel generator set shutdown cooling without idling, less oil will make the friction surface, when the engine starts again increased due to poor lubrication and wear. Therefore, diesel generators should be removable flame front load, and gradually reduce the speed, no-load running a few minutes.
